Jet dryers are modern devices with high efficiency and low energy consumption that have found their application in public toilets. Using a strong air stream, these dryers are able to remove moisture from hands in a few seconds, which is much faster and more efficient than traditional dryers. Despite higher initial costs, jet hand dryers allow for reducing long-term maintenance costs and improve the functioning of public toilets by increasing the speed and effectiveness of drying. They have also been designed to increase hygiene, thanks to the use of antibacterial housings and HEPA filters.
